(GRANTED UNDER THE PROVISIONSOF THE ACT 0F MARCH 3, 1921, 41 STAT. L.1313.) i

To all whom it may concern:

Be itknown that 1, Max Jonas, a citizen of the German Republic, andresident of Berlin S. 42,, Germany, have invented certain new and usefulImprovements in and Relatingto Clamping and Stretching'Devices forTrousers (forv which Iliave filed application in Germany June 15, 1920),of which the following is a specification.

My present invention relates to clamping and stretching devicesfortrousers and has for its object to provide an improved device of thiskind, comprising a pair of spring clamps connected in a particular waywith an intermediate hanger.

In carrying my invention into practice,

I use a pair of spring clamps or clips the.

two arms of each clamp or clip being pivotally and frictionally held ona spool shaped pivot-pin, provided with a suitable bore,

having an inner spring and slidably engaged by one side arm of theintermediate hanger, whereby said clips may be moved and held apart fromeach other after having engaged the lower borders of the trousers fcl rthe purpose of stretching the same latera ly.

In my improved stretching device thepiv oting arms of each clip areconnected together below said pivot-pin by means of a traction springsecured to said arms by pins passing through the arms of the clip.

Moreover the lower ends of the arms of each clip have their inner facesprovided with upwardly projecting teeth and serving to secure a perfecthold of the clipson the.

borders of the trousers.

My invention will be readily understood from the following descriptiontaken in connection with the accompanying drawings, wherein:

Fig. 1 is a perspective view of the device showing a pair of trousers,engaged by the same.

Fig. 2 is a perspective view of a clip in 1 Fig. 6' is an elevation ofthe complete device in its collapsed position. v v

Referring to the drawings, 1,1, designate two springclips, eachof whichcomprises two arms connected together by. means of a coilspring 2, theends of which are held in circular openings 3,-provided in said arms,

. Above said coil-spring 2 each arm of the clip has a semi-circularrecess to receive a cylindrical spool-shaped pivot-pin 6,. provided withend disks 7 adapted to engage the sides of the arms, whereby. any unduelateral movement of the arms with respect to each other will beeffectively avoided. Said pivotpin 6 is provided with a central bore 8,which is preferably rectangular in cross section although it may be ofany desired shape to receive the correspondingly. shaped arm 9therethrough, said arm 9 being frictionally held in said bore by thepressure ofa small spring blade (not shown) secured within said bore 8in a well known manner. The

inner ends of the arms 9 are pivotally connected to a supporting block10 which isprovidedwith the usual hanger 11 Thus it will be seen thatsaid clips l are adapted to be shifted along said arms 9 and thisarrangement forms an important feature of my invention. i

The operation. of the invention will be readily understood from theconstruction above described.

The arms 9 of the hanger being in their horizontal positions as shown inFig. 1 and the clips 1,1 arranged on said arms, the borders of a pair oftrousers may be clamped between the jaws of said clips as shown,whereupon said clips will be shifted apart I from each other on saidarms9 to stretch the borders of said trousers.

As shown in Fig. 6 the arms 9 may be moved in vertical parallelpositions, whereby the device may be easily packed.

I wish itto be understood that minor details of construction may bechanged without departing from the scope of the invention.

Having now fully described my said invention, what I claim and desire tosecure by Letters Patent, is:

1. In a device of the class described, the combination with a hangerhaving a pair of arms thereon, of a spool slidably mounted on each arm,a pair of arms for each spool, each arm engaging the spool on anopposite side, and resilient means connecting the arms of each pair andserving to pull said arms together, so that the arms will engage thespool and the free end of the arms will be drawn toward each otherforgripping material to be held.

2. The combination with a licnger of a pair of spools slidably mountedthereon, a pair of arms for each spool having a bearing portion betweenthe ends for engaging the spool and teeth formed on the innerfaces atone end portion, and a spring connecting the arms of each pairpositioned between the bearing portion and the toothed ends,

newness whereby the spring will draw the arms together so that the teethwill engage material to be held and the bearing portion will engage thespool.

3. The combination with a hanger of a pair of cylindrical membersslidably mounted thereon, a pair of arms for each cylindrical member,each pair of arms being formed with teeth on the inner side adjacent oneend, and cylindrical bearing portions between the ends for engaging theperiphery of the cylindrical members, and a spring connecting the armsof each pair between the toothed portion and the bearing portion fordrawing said arms together so that the cylindrical portions willfrictionally engage the cylindrical member and the teeth will engagematerial to be held.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.
